“…They improve the periodic download method and provide a new way to schedule the video segments. Besides, a scheme that can control the quality of service is designed by Son et al [13]. The relative one-way delay trend is used to determine whether the required bandwidth is available in this scheme.…”

Adaptive streaming over Hypertext Transport Protocol (HTTP) has been widely used for the transmission of video content. Most of the existing studies about HTTP adaptive streaming (HAS) concentrate on improving resource efficiency, fairness among users, and quality of service for single-source videos. However, there is a growing number of live streaming applications, such as video-casts of courses, where service providers want to transmit video streams of different scenes simultaneously over the bandwidth-constrained network. Since concurrent streams further deteriorate the insufficient bandwidth situation, a systematic solution is highly needed to utilize the resources efficiently and guarantee the quality of multi-view video services. In this paper, we propose a priority-based adaptive scheme for multi-view live streaming based on HTTP streaming. Firstly, we adopt an integrated bandwidth prediction approach to calculate the available bandwidth, solving the low bandwidth utilization problem existing in the benchmark method. Secondly, we design a unified segment request strategy to restrict the interval between each request, and guarantee the synchronization of different live video streams. Finally, an adaptive scheduling algorithm is proposed with respect to priorities, to dynamically adjust the quality level of multiple video streams and improve the quality of multi-view video service. Simulations show that the proposed scheme makes considerable improvements compared to the benchmarks.

“…Proposed solutions include better adaptation logic on client side that implements enhanced bandwidth estimation [9], using specific codecs, namely H.264 Scalable Video Coding extension (SVC) for content preparation instead of H.264 Advanced Video Coding (AVC) in order to allow better caching performance of underlying network and hence better hit ratio [10,11]. In [12] authors proposed fast estimation of available bandwidth that can be implemented in adaptation logic at the client. All of these proposed solutions either require significant additions to common workflow or they require client side modifications.…”

“…1, the encoded symbols with degree 1 are fully used, while the usage ratio of encoded symbols decreases extremely along with degree increasing, especially for small overhead. Here the usage ratio of encoded symbols is defined as the proportion of the helpful symbols in the whole encoded symbols with degree i, as expressed in (2).…”

“…However, the bandwidth is quite hard to predict and is changing over time even though there have been various bandwidth estimating methods proposed in previous papers [2]- [4]. Therefore, misestimating the fluctuant bandwidth would lead to poor performance on self-adaptation to bandwidth for adaptive streaming.…”

SUMMARYIn this paper, we design an Unequal Error Protection (UEP) rateless code with special coding graph and apply it to propose a novel HTTP adaptive streaming based on UEP rateless code (HASUR). Our designed UEP rateless code provides high diversity on decoding probability and priority for data in different important level with overhead smaller than 0.27. By adopting this UEP rateless channel coding and scalable video source coding, our HASUR ensures symbols with basic quality to be decoded first to guarantee fluent playback experience. Besides, it also provides multiple layers to ensure the most suitable quality for fluctuant bandwidth and packet loss rate (PLR) without estimating them in advance. We evaluate our HASUR against the alternative solutions. Simulation results show that HASUR provides higher video quality and more adapts to bandwidth and PLR than other two commercial schemes under End-to-End transmission. key words: adaptive streaming, decode probability and priority, overhead, rateless code, unequal error protection, video quality
